Embrace Raf Simons’ experimental approach to tailoring with this offbeat cotton-poplin shirt from Calvin Klein 205W39NYC. The red, white and blue stripes form a subtle nod to the brand’s classic American DNA, while more unexpected details include oversize flapped welt pockets at the front and button fastenings at the rear. The streamlined silhouette is completed with a thin stand collar and slits along the sides. Highlight this shirt’s simple appeal by pairing with winter layers.
